One word, bull-fucking-shit. Here smartass, I made a list just for you :
''Bound by Love'' - Previosuly knows as ''Until "My Girlfriend" is Pregnant - Abduction, Confinement, Impregnation'' used to be garbaged Mtl and I mean real nonsensical crap, ended up getting a proper translation.
''Ambrosia'' - Used to be mtl, got official translation
''Horny Bunny Hana''- Used to be MTL, got a fan translation by EldenFZ.
''Explorer Of Yggdrasil'' - Again, originally uploaded as Mtl, got translated last year.
''Exile of Summon Princess Puri Stella''- started out as a MTL partial, got fully fan translated.
''Lisa and the Grimoire''- used to be called ''Risa and the Succubus Grimoire (machine translated and edited), got a proper translation despite that.
''Scars of Summer'' - Uploaded not only as Mtl but partial Mtl, ended up with a proper translation last year.
''Crimson Colosseum'' - used to be ''The Girl In The Red Slave Collar''.
''Obscurite Magie: The City of Sin''- Used to be MTL, then got a proper fan translation released here, and lastly it even got a official translation release from Kagura, so full evolution from MTL, to fan-transaltion to official translation.
''Tower of Ardia''- used to be a partial MTL, though it was never uploaded here untill the complete and proper translation, still it did use to be MTL.
''Fox Girls Never Play Dirty''- Originally posted here under the name ''Furry Eared Girls Never Betray'', you guessed it, MTL.
''Country Girl Keiko'' - used to have a fan translation, don't know how good it was since I believe only the official was uploaded here, still worth mentioning, since it was a game that already had a translation, but still got an officia one.
'' Fools of the Philosopher's Tower''- used to be partial Mtl, got an official translation.
Here's some titles which have bad and unstable MTL yet will be properly translated in the future :
''Knights Of Messiah'' -
''The Pregcess Of Zeven''
''Samurai Vandalism'' ( ok this one has a shitty official english version, but it's so bad it might aswell be MTL tier ).
''The Heart Of Darkness''.
I'm confident I could find a dozen more but it's fcking late as hell so to sum it up, If a game gets MTL'd, and if it's a good game that people desperately want to play, they'l make noise, leading to it getting a good translation, be it either a fan made one or from groups like Kagura games.
